scope:

This International Standard specifies the characteristics of a cotton material and the preliminary treatments which are to be applied to it in order to make it an unsoiled cotton control cloth for the testing of certain effects of laundering. It also defines the conditions of use of this control cloth (in the form of control test pieces) during the laundering processes which are being tested from the point of view of the conservation of the original characteristics of the cloth. The unsoiled cotton control cloth is primarily intended to enable the laundering of white cloth to be tested. It may be used with all detergents and all types of domestic or industrial machines designed to wash, hydroextract and dry household textile articles. The unsoiled cotton control cloth may also be used for testing the laundering of other categories of textile articles (coloured, for example).
